It will be understood that the car isconstructed so as to provide a nun'iber of dumping openings on oppositesides of the centersill, these openings being normally closed by hingedbottom sections or doors which are manipulated by apparatus which formsno part of the present invention and which, therefore, has been omittedfrom the drawings. This invention concerns the construction of a doorsuitable for use in a car of this type, or with other dumping cars wheresimilar conditions prevail.

The door consists of a sheet metal panel 15 preferably, although notnecessarily, composed of ay single sheet of metal. The door sheet, as itmay be termed, is formed with a kcentral corrugated portion 16 and atone edge is hinged to the center sill 10 (the hinges being indicated at17). marginal portions-18, 16 of the door sheet and the sider marginalportion 19 thereof `which bears against the under side of the inturnedpart 20 of the side sheet 12 are in the same plane, thatis, the originalplane of the sheet before it is pressed. The corrugated portion 16 ofthe sheet is formed by pressing therein, in parallel arrangement, aplurality of ribs which alternately project above and below the originalplane of the sheet. Those projecting upwardly preferably have theircrests in a plane at the level of the cross bearer cover plates 14 andthe intervening. center sill cover plates (not shown). v.The hingedmargin 22 of the sheet is depressed to the level of the bottoms of 4the.depressed corrugations. this arrangement any moisture will drain olfalong the depressed edge 22 of the plate instead of being trapped aswould be the case if both ends of the corrugations were below, the levelof the adjacent uncorrugated margins. The corrugations are lmade toterminate within the edges of the sheet so that they will give itrigidity. l The configuration 'of the sheet as shownfalso adapts it toht snugly in place underthe center sill and side sheets. The centerysill is shown as consisting in part of T-beam 23 and inA order that thedoor may project under the upper flange of this T- bearntheextremitiesof the marginal portions 18 adjacent the center sill are"depressed, as indicatedat 24, to the level of the marginal portion 22ofthe sheet'. To give additional strength and rigidity to the door itsedges are formed with downturned flanges 25. In addition a rigidifyingstructure is provided for. the lunder side of the door comprising anglebars 26 running parallel with the corrugations and secured by rivets 27to the marginal portions 18 of the door'and tothe flanges 25, with theinterpositin of spacers 28, by rivets 29, together with a'Z-bar 30secured to the members 26 The end and to the door sheet and extendingacross the ends of the corrugations and angle bars 3l. near the oppositeedge of the door which are riveted to the door at suitable intervals.

I claim:

l. In combination with a railway ear having a dumping openingl in thebottom, a sheet metal door to close the same formed with strengtheningcorrugations which terminate within the edges of the door sheet, saiddoor sheet being formed so that portions of the corrugations projectbelow the plane of adjacent uncorrugatcd parts of the sheet. while thecorrugations at one end are cntirelyab ve the uncorrugated marginal partof the sieet adjacent thereto for Llrninagi` purposes.

In combination with a railway cal' having a door opening in the bottom,:i sheet metal door to close the same formed with a plurality ofcorrugations extending across the door sheet between opposite edges, theportions of the corrugations adjacent one of said edges projecting belowthe adjacent marginal parts of the sheet while the opposite ends of thecorrugations stand substantially above the uncorrugated part of themarginal sheet adjacent thereto.

3. In combination with a railway car having a door opening in thebottom, a sheet metaldoor to close the same formed with :t plurality ofparallel corrugations extending 'across the door sheetbetween oppositeedges at right angles to said edges, the portions of the corrugationsadjacent one of said edges projecting below the adjacent marginal partsof the sheet while the opposite ends of the corrugations standsubstantially above the un'corrugated part of the marginal sheetadjacent thereto.

4. In combination with a raihvay car hat ing a dumping opening in thebottom, a sheet metal door to close thc same formed with a depressedportion which extends to one edge of the door sheet, said depressedportion having pressed therein corrugations upstanding therefrom whichterminate within the edges of the sheet.

5. In combination with a railway car haw ingga dumping opening in thebottom, n. sheet metal door to close the same formed with a depressedportion which extends to one edge of the door sheet, said depressedportion having pressed therein (.orrugations upstanding therefrom whichextend toward but terminate short of said edge.

6. In combination with a railway car having a dumping opening in thebottom` a sheet metal door to close the same formed with a depressedportion which` extends to one edge of the door sheet, said depressedportion having pressed therein a plurality is Closed and the holloxrs ofwhich merge' into the snrfaeeoi" described.
